Options

-LDe: Pulse/Ramp Sequence

Following output controls of A to C are applicable.

A. Pulse Sequence

Sequential operation is possible by using voltage and current set on each memory a, b, and c in combination with multi-set functions. Not only continuous operation, but also it is possible to specify the times.

It is the best fit evaluation test for products as various operations, like as repeat of a and b only or repeat of b, c and off only, are enabled by setting time of memory a, b, c or off to 0.0.

This graph is Pulse sequence.

ta, tb, tc, and toff can be set respectively in 0.0 s to 9999 h 59 m 59.9 s.

B. Ramp

It enables to make ramp action up to set voltage or current (or from the set voltage or current to 0 V or 0 A). It is useful to like to rise (reduce) voltage or current slowly.

* As for the lamp operation, you can select "Both setting voltage and current", "Voltage setting only", or "Current setting only".

This graph is Ramp.

t1 and t2 can be set respectively in 0.0 to 9999 h 59 m 59.9 s.

C. Combination of Pulse and Ramp Sequence

It is also possible to use pulse sequence combined with ramp action. If the multi-set function is combined with the too, it is able to make sequence action by using voltage or current set on memory a, b and c. Not only continuous operation, but also it is possible to specify the times.

It is useful in various aspects as it is possible to rise (reduce) voltage or current slowly up to 20 set value.

This graph is Combination of Pulse and Ramp Sequence.

t1 to t4, ta to tc and toff can be set respectively in 0.0 s to 9999 h 59 m 59.9 s.

-LGob: Optical Interface Board

With optical communication, galvanic isolation control is performed. As complete isolation is performed by means of optical fiber, this enables advance prevention of erroneous operation involved with transient phenomenon caused by surges, inductive lightning, external noise, etc.
And, the control via SCPI command is also available.

  • -LGob: Optical interface board + optical cable 2 meters
  • -LGob(Fc5): Optical interface board + optical cable 5 meters

  • Noisy environment including factories (Example: Motors or coils are used near power supplies and loads).
  • Using with high voltage floating (more than 250 V).
  • Installation distance of 2 meters or more between the high voltage power supply and a controller such as a computer, laptop, or Programmable Logic Controller (PLC).
